TAKATA RECALL: I'M HAVING IDLE/STALLING ISSUES WITH MY 2009 GMC ACADIA. CAR CUTS OFF WHILE DRIVING CAUSING A SAFETY HAZARD. FIRST, I HAD MY CAR INSPECTED BY LOCAL LICENSED MECHANIC WHO DIAGNOSED A TIMING CHAIN ISSUE AND CAT CONVERTER ISSUE. I FOLLOWED BY CALL A GMC DEALER AND INFORMING THEM OF MY CAR PROBLEMS. THEY SCHEDULED MY CAR FOR AN INSPECTION SINCE THEY HAVE AN EXTENDED WARRANTY FOR TIMING CHAINS. THEY INSPECTED MY VEHICLE AND INFORMED ME SINCE THE TIMING CHAIN WASN'T MAKING NOISES THEY WOULDN'T DIAGNOSE IT AS A PROBLEM. THEY RELEASED MY CAR WITHOUT FIXING IT AND MY CAR STILL CUTS OFF AND IDLES WHILE DRIVING. THEY ALSO TOLD ME ABOUT MANY OTHER ISSUES FOUND DURING THE DIAGNOSTIC TOTALING OVER $8000 IN REPAIRS. I CALLED AND COMPLAINED TO GMC AND THEY INFORMED ME THAT THEIR ARE ACTUALLY MANY OTHER ADDITIONAL PARTS WARRANTY'S/COVERAGES THAT THEY HAVE AND MAY BE ABLE TO ASSIST ME WITH. I FIND THIS VERY CONCERNING AS THE GMC DEALERSHIP REFUSED TO PROPERLY DIAGNOSE AND SERVICE MY VEHICLE, ALONG WITH THE FACT THAT GMC HAS SECRET ADDITIONAL WANRRANTIES/COVERAGES THAT THE GENERAL PUBLIC DOESN'T KNOW ABOUT MY CAR WAS IN THE GMC DEALER SHOP FOR 4 DAYS AND THEY REFUSED TO ASSIST ME WITH A LOANER VEHICLE WHILE MY CAR WAS BEING INSPECTED. THEY RELEASED MY VEHICLE AND NOW I'M BACK TO SQUARE ONE WITH THE SAME ISSUES AND NEW LIST OF SUPPOSEDLY FOUND CAR ISSUES ESTIMATING OVER $8,000.

WHEN ACCELERATING, MY CAR SEEMS TO 'SLIP' OR 'STUTTER' BEFORE CLICKING INTO GEAR. THIS HAPPENED IN THE FIRST YEAR OF OWNERSHIP. THE DEALERSHIP NEVER ACKNOWLEDGED IT WHEN I WOULD BRING IT IN TO GET CHECKED. AFTER A FEW YEARS OF OWNING IT I NOW KNOW THAT IT IS A TRANSMISSION ISSUE VERY COMMON WITH THE GMC ACADIA. I HAVE READ THAT IT IS A FAULTY WAVE PLATE. NOT SURE WHAT THAT IS BUT NOW WITH ONLY 50,000 ON MY CAR IT IS REALLY BAD. IT BARELY MADE IT HOME LAST NIGHT. TRANSMISSION IS TOTALLY SLIPPING AND EVEN WHEN JUST DRIVING ALONG AT THE SAME SPEED IT WENT INTO LIMP MODE. THE GAS REVVED LIKE I WAS IN NEUTRAL. THIS IS EXTREMELY DANGEROUS AS I HAD A CARLOAD OF GIRLS ON A TRIP TO THE MOUNTAINS. WHAT IS IT GOING TO TAKE UNTIL THIS CAUSES AN ACCIDENT AND CASUALTIES! GMC NEEDS TO STEP UP AND GET THIS PART RECALLED. IT IS A FAULTY PART AND THEY NEED TO PAY FOR THE REPLACEMENT!!! *TR
THE ABOVE MILEAGE AND DATES ARE APPROXIMATE--DEALER AND GMC (CASE #[XXX]) ARE AWARE OF PROBLEM WHICH INVOLVES A SUDDEN POWER SURGE AS I HAVE BEEN STOPPING AT MY MAILBOX, STOPPING AT STOP SIGN AND PULLING INTO PARKING PLACE. EACH TIME MY SPEED WAS SLOW ENOUGH AND MY FOOT WAS ON THE BRAKE, THAT I COULD MAINTAIN CONTROL WHILE THE RPMS SURGED TO OVER 4,000. I PUT TRANSMISSION INTO NEUTRAL AND SHUT ENGINE OFF AND, WITH RESTART, PROBLEM WENT AWAY. DEALER HAS ATTACHED A MONITOR TO TRY TO IDENTIFY THE ERROR CODE, BUT AFTER A FEW WEEKS OF HAVING IT IN PLACE, I RETURNED TO DEALERSHIP AND HAD IT REMOVED. THE FOLLOWING MORNING IT HAPPENED AGAIN AS I STOPPED AT MY MAILBOX. I HAVEN'T BEEN BACK TO MY DEALER TO REPORT THAT INCIDENT. VEHICLE NOW HAS JUST A FEW MILES OVER 101,000 AND THERE HAS BEEN NO RECENT ISSUE OF THE SAME TYPE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
